Description
Dispositif d'assistance respiratoire.
La présente invention a pour objet un dispositif d'assistance respi-ratoire, utilisable sur des patients dont la respiration spontanée est ab-sente ou insuffisante, qu'ils soient ou non placés sous respiration artifi-cielle.
Par le brevet européen EP-A-O 390 684 (US-A-5 036 847), on connaît déjà un dispositif d'assistance respiratoire tubulaire, qui forme un canal principal et qui est destiné à être relié par son extrémité distale à
une voie respiratoire d'un patient pour que ledit canal principal relie à
l'extérieur le système respiratoire dudit patient, ledit dispositif comportant au moins un canal auxiliaire associé à des moyens de déflexion pour in-jecter un jet de gaz respiratoire défléchi vers l'intérieur dudit canal princi-pal et destiné à la ventilation dudit patient.
La présente invention a pour objet de perfectionner un tel disposi-tif afin que le praticien puisse connaître la pression gazeuse et/ou la com-position gazeuse dans ladite voie respiratoire du patient.
A cette fin, selon l'invention, le dispositif d'assistance respiratoire du type rappelé ci-dessus, est remarquable en ce qu'il comporte, du côté
distal, une chambre annulaire, disposée à la périphérie dudit dispositif tu-bulaire, coaxialement à celui-ci et communiquant avec le système respira-toire du patient par l'intermédiaire de l'orifice formé par sa section annu-laire distale, et en ce que ladite chambre annulaire est pourvue de moyens de liaison avec l'extérieur.
Ainsi, il est possible de mesurer la pression et/ou de déterminer la composition du gaz se trouvant dans ladite chambre. On remarquera que ce gaz est identique à celui régnant dans le système respiratoire, mais est assagi par rapport à celui-ci, du fait de son isolation partielle par la cham- Respiratory assistance device.
The present invention relates to a respiratory assistance device for use in patients whose spontaneous breathing is ab-or not, whether or not they are under artificial respiration.
cial.
By the European patent EP-AO 390 684 (US-A-5,036,847), already knows a tubular respiratory assistance device, which forms a main channel and which is intended to be connected by its distal end to a patient's respiratory tract so that said main canal connects to outside the respiratory system of said patient, said device comprising at least one auxiliary channel associated with deflection means for in-injecting a jet of breathing gas deflected into said main channel pal and intended for ventilation of said patient.
The object of the present invention is to improve such a device so that the practitioner can know the gas pressure and / or gas position in said respiratory tract of the patient.
For this purpose, according to the invention, the respiratory assistance device of the type recalled above, is remarkable in that it includes, on the distal, an annular chamber disposed at the periphery of said device bile, coaxially with it and communicating with the respiratory system.
patient through the orifice formed by its annular section.
distal surface, and in that said annular chamber is provided with means of connection with the outside.
Thus, it is possible to measure the pressure and / or determine the composition of the gas in said chamber. We will notice that this gas is identical to that prevailing in the respiratory system, but is the latter, because of its partial isolation by the
2 bre. Les mesures sont donc fiables, en évitant les conséquences des tur-bulences gazeuses.
Notamment à des fins d'homogénéisation du gaz contenu dans la chambre, il est alors préférable que lesdits moyens de liaison avec l'exté-rieur soient disposés à l'extrémité proximale de ladite chambre.
Dans le cas où les gaz se trouvant dans ladite chambre doivent faire l'objet d'une analyse de composition et d'une mesure de pression, ladite chambre doit présenter un volume relativement grand, correspon-dant à la quantité de gaz nécessaire à l'analyse. Il peut alors se produire, lo dans ladite chambre, des turbulences susceptibles d'induire de fortes va-riations dans les mesures de pression.
Pour éviter cela, il est avantageux de disposer, dans ladite cham-bre, des moyens d'amortissement de turbulences gazeuses, tels qu'un filtre fibreux ou poreux.
A titre de sécurité supplémentaire à un éventuel dispositif de me-sure de pression, il est avantageux que le dispositif conforme à la pré-sente invention comporte un réseau de rainures pratiquées dans la paroi du canal principal et au moins un orifice traversant !a partie proximale dudit dispositif, de façon à former une mise à l'air libre du système respi-ratoire dudit patient, en cas de bouchage accidentel de la partie proximale dudit dispositif.
Le dispositif d'assistance respiratoire tubulaire conforme à la pré-sente invention peut trouver de nombreuses applications. Il peut être utili-sé comme sonde buccale ou nasale, ou bien encore comme embout rap-porté à un tube de trachéotomie. Il peut également, dans un masque res-piratoire destiné à être appliqué sur le visage d'un patient, constituer l'embout tubulaire d'entrée et de sortie du gaz respiratoire. Dans ce cas, ladite chambre est en communication avec le système respiratoire du pa-tient par l'intermédiaire de l'intérieur dudit masque.
WO 99/21602 ber. The measures are therefore reliable, avoiding the consequences of gassy bulbs.
In particular for the purposes of homogenisation of the gas contained in the room, it is then preferable that said connection means with the outside are located at the proximal end of the chamber.
In the case where the gases in that chamber are be subject to a composition analysis and a pressure measurement, said chamber must have a relatively large volume, corresponding to the amount of gas required for analysis. It can then happen, lo in said chamber, turbulences likely to induce strong fluctuations in the pressure measurements.
To avoid this, it is advantageous to have, in said room, apparatus, means for damping gaseous turbulence, such as a fibrous or porous filter.
As additional security to a possible device for of pressure, it is advantageous that the device conforms to the pre-This invention comprises a network of grooves formed in the wall of the main canal and at least one through-hole!
said device, so as to form a venting of the respiratory system.
said patient, in the event of accidental obstruction of the proximal said device.
The tubular respiratory assistance device according to the present invention This invention can find many applications. It can be used as an oral or nasal probe, or as a quick-release carried to a tracheostomy tube. He can also, in a mask a piratory intended to be applied to the face of a patient, to constitute the tubular inlet and outlet end of the breathing gas. In that case, said chamber is in communication with the respiratory system of the holds via the interior of said mask.
WO 99/2160
3 PCT/FR98/02280 Lorsqu'il est utilisé comme embout de masque respiratoire, le dis-positif d'assistance respiratoire conforme à la présente invention peut être solidaire dudit masque. Cependant, notamment pour pouvoir être utilisé
seul, sans masque, il peut être avantageux que ledit dispositif soit monté
de façon amovible, par exemple par emboîtement, sur ledit masque.
Les figures du dessin annexé feront bien comprendre comment l'invention peut être réalisée. Sur ces figures, des références identiques désignent des éléments semblables.
La figure 1 est une vue schématique, partiellement en coupe axiale, d'un masque d'assistance respiratoire comportant un dispositif tubulaire conforme à la présente invention.
La figure 2 montre, en coupe axiale, ledit dispositif tubulaire cons-tituant l'embout du masque de la figure 1.
Les figures 3, 4 et 5 sont des coupes transversales du dispositif de la figure 2, respectivement selon les lignes III-lll, IV-IV et V-V.
La figure 6 montre, en coupe axiale semblable à la figure 2, une variante de réalisation du dispositif tubulaire conforme à la présente in-vention.
Les figures 7, 8 et 9 sont des coupes transversales du dispositif de la figure 6, respectivement selon les lignes VII-VII, VIII-VIII et IX-IX.
Le masque d'assistance respiratoire 1, conforme à la présente in-vention et représenté sur la figure 1, comporte une coque rigide de forme générale tronconique 2, pouvant être appliquée sur le visage 3 d'un pa-tient par l'intermédiaire d'un coussinet gonflable 4, bordant son ouverture périphérique. Du côté opposé, ledit masque 1 comporte un dispositif tu-bulaire 5, fixé ou emboîté sur une saillie tubulaire 6 de ladite coque 2. Le dispositif tubulaire 5 sert d'embout d'entrée et de sortie de gaz respira-toire dans le masque 1. Eventuellement, il peut être relié à un appareil de respiration artificielle par son extrémité proximale (opposée au patient 3). 3 PCT / FR98 / 02280 When used as a respirator mouthpiece, the positive respiratory assistance according to the present invention can be integral with said mask. However, in particular to be able to be used alone, without a mask, it may be advantageous for said device to be mounted removably, for example by interlocking, on said mask.
The figures of the annexed drawing will make clear how the invention can be realized. In these figures, identical references designate similar elements.
FIG. 1 is a schematic view, partly in section axial, a respirator mask with a device tubular according to the present invention.
FIG. 2 shows, in axial section, said tubular device constituting the mouthpiece of the mask of FIG.
Figures 3, 4 and 5 are cross sections of the device of Figure 2 respectively along the lines III-III, IV-IV and VV.

variant embodiment of the tubular device according to the present invention.
vention.
Figures 7, 8 and 9 are cross sections of the device of Figure 6 respectively along the lines VII-VII, VIII-VIII and IX-IX.
Respiratory assistance mask 1, in accordance with the present in-vention and shown in Figure 1, comprises a rigid form shell truncated cone 2, which can be applied to the face 3 of a pa-holds via an inflatable pad 4, bordering its opening peripheral. On the opposite side, said mask 1 comprises a device 5, fixed or fitted on a tubular projection 6 of said shell 2.
tubular device 5 serves as a mouthpiece for entering and leaving breathing gas.
in the mask 1. Optionally, it can be connected to a artificial respiration by its proximal end (opposite to patient 3).
4 Comme le montrent plus en détail les figures 2 à 5, le dispositif tubulaire 5 comporte un passage traversant interne 7 et, en partie mé-diane, une paroi conique 8, saillant à l'intérieur dudit passage 7. La paroi conique 8 a pour objet de défléchir, en direction de l'axe du passage 7, des jets de gaz respiratoire injectés par des canaux périphériques 9, ali-mentés à partir d'un embout d'amenée 10, par l'intermédiaire d'une chambre annulaire périphérique 11.
Par ailleurs, du côté distal, le dispositif tubulaire 5 comporte une chambre périphérique annulaire 12, coaxiale audit dispositif 5. La cham-bre périphérique annulaire 12 communique avec l'intérieur du masque 1 par son orifice annulaire distal 13 et est pourvue, à son extrémité proxi-male, d'un embout de sortie 14.
Un filtre 15, fibreux ou poreux (coton, mousse synthétique, etc ...) est disposé dans la chambre périphérique annulaire 12, pour amortir les turbulences gazeuses et, par suite, les trop fortes variations de pression.
Comme cela est représenté sur la figure 1, ('embout de sortie 14 peut être relié à un analyseur de gaz 16 et à un dispositif de mesure de pression 17. Bien entendu, les liaisons 18 et 19 entre l'embout de sortie 14 et les dispositifs 16 et 17 sont prévues pour que le prélèvement de gaz à analyser par la liaison 18 n'ait pas d'influence sur la mesure de pression, via la liaison 19.
Ainsi, grâce aux dispositifs 16 et 17, le praticien assistant le pa-tient 3 connaît en permanence la composition du gaz dans le masque 1 (et notamment sa teneur en gaz carbonique) et la pression à l'intérieur dudit masque. Il peut donc prendre les mesures d'intervention appro-priées en fonction desdites composition et pression du gaz.
Dans la variante de réalisation du dispositif 5, montrée par les fi-gures 6 à 9, on retrouve les éléments 7 à 15 précédemment décrits en regard des figures 2 à 5. Cependant, on peut remarquer que cette va-riante de réalisation comporte de plus, dans la paroi du passage 7 et dans la paroi conique 8, des rainures 20, 21, 22 disposées radialement entre les canaux périphériques 9, ainsi qu'au moins un orifice 23 traversant la 4 As shown in more detail in FIGS. 2 to 5, the device tubular 5 has an internal through-passage 7 and, in part, diane, a conical wall 8 projecting inside said passage 7. The wall 8 is intended to deflect towards the axis of passage 7, jets of respiratory gas injected by peripheral channels 9, food from a delivery nozzle 10, via a annular peripheral chamber 11.
Furthermore, on the distal side, the tubular device 5 comprises a annular peripheral chamber 12, coaxial with said device 5. The chamber Ring peripheral 12 communicates with the inside of the mask 1 through its distal annular orifice 13 and is provided at its proximal end with male, an outlet tip 14.
A filter 15, fibrous or porous (cotton, synthetic foam, etc ...) is arranged in the annular peripheral chamber 12, for dampen gaseous turbulence and, as a result, too much variation pressure.
As shown in Fig. 1, (outlet tip 14 can be connected to a gas analyzer 16 and to a measuring device of pressure 17. Of course, the links 18 and 19 between the mouthpiece 14 and the devices 16 and 17 are provided so that the sampling of gas to be analyzed by the link 18 has no influence on the measurement of pressure, via the link 19.
Thus, thanks to the devices 16 and 17, the practitioner assisting the patient holds 3 continuously knows the composition of the gas in the mask 1 (including its carbon dioxide content) and the pressure inside said mask. It can therefore take the appropriate intervention measures according to said composition and gas pressure.
In the embodiment variant of the device 5, shown by FIGS.
6 to 9, we find the elements 7 to 15 previously described in Figures 2 to 5. However, we can notice that this In addition, in the wall of passage 7 and in the conical wall 8, grooves 20, 21, 22 arranged radially between the peripheral channels 9, as well as at least one orifice 23 passing through the
5 paroi de l'extrémité proximale du dispositif 5. Ainsi, si pour une raison quelconque la partie proximale du dispositif 5 est bouchée, les rainures 20, 21, 22 et les orifices 23 constituent une mise à l'air libre évitant à la pression du gaz respiratoire injecté d'atteindre des valeurs excessives, susceptibles d'être préjudiciables au patient. On obtient ainsi une sécurité
de fonctionnement automatique, complétant l'éventuel dispositif de me-sure de pression 17.
Bien que sur les figures, on ne les ait pas respectés, il va de soi que le dispositif 5 peut comporter des canaux ou conduits d'injection de médicaments et/ou d'eau.
Par ailleurs, bien que ci-dessus on ait décrit, à l'aide desdites figu-res, une application particulière du dispositif 5 à un masque respiratoire, on comprendra aisément que ledit dispositif peut trouver de nombreuses autres applications, par exemple comme sonde nasale, sonde buccale, sonde trachéale, etc ... Bien entendu, les dimensions dudit dispositif sont adaptées à chaque utilisation particulière. 5 wall of the proximal end of the device 5. So, if for a reason any proximal part of the device 5 is plugged, the grooves 20, 21, 22 and the orifices 23 constitute a venting avoiding the pressure of the injected respiratory gas to reach excessive values, likely to be detrimental to the patient. This provides security automatic operation, completing the eventual device for pressure 17.
Although on the figures, we did not respect them, it goes without saying that the device 5 may comprise channels or injection ducts of medicines and / or water.
Moreover, although above, it has been described with the help of res, a particular application of the device 5 to a respirator, it will be readily understood that said device can find many other applications, for example as nasal probes, oral tracheal probe, etc. Of course, the dimensions of said device are adapted to each particular use.
